Patrol unmanned rotorcraft

[0016] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so that the protection scope of the present invention can be more clearly defined.

[0017] See figure 1 As shown, a patrol rotor drone of the present invention includes a drone 1. A pair of horizontal guide rails 2 are installed symmetrically along the vertical plane of the drone 1. The horizontal guide rail 2 is made of insulating material, and the horizontal guide rail 2 There are conductive strips 3 connected to the bottom. Two conductive strips 3 are electrically connected to the voltage detection unit 4 in the drone. Each horizontal rail 2 is equipped with a walking device 5, and each walking device 5 is installed with one Hall sensor assembly 6. Since a pair of horizontal guide rails 2 are installed on the UAV 1, by controlling the UAV 1 to stop between the two wires 7 of the high voltage line, the conductive strips 3 on both sides are in contact with the two wires 7, which can be easily detected The voltage on the high-voltage line and the Hall sensor assembly 6 on the horizontal guide rail 2 can detect the current on the high-voltage line. With the inspection rotor drone, there is no need to manually climb the high-voltage line tower. The detection personnel are far away from the high-voltage line and there is no danger of electric shock.

[0018] See figure 2 , image 3 As shown, the Hall sensor assembly 6 includes an insulating C-shaped frame 61 connected to the walking device 5. The upper and lower ends of the insulating C-shaped frame 61 are respectively hinged with an upper conductive semicircular ring 62 and a lower conductive semicircular ring 63, and the upper conductive semicircle The inner ring of the circular ring 62 and the lower conductive semicircular ring 63 is also provided with an insulating layer 64, and the middle of the insulating C-shaped frame 61 is also horizontally provided with a spring mounting cylinder 65. The spring mounting cylinder 65 is equipped with a compression spring 66 and a compression spring 66. One end of the upper conductive semicircular ring 62 and one end of the lower conductive semicircular ring 63 are pressed tightly, and the upper conductive semicircular ring 62 and the lower conductive semicircular ring 63 are also electrically connected to the Hall current detection unit 67. When the drone needs to detect the current of the high-voltage line, by driving the walking device 5 to move in the direction of the drone, the upper conductive semicircular ring 62 and the lower conductive semicircular ring 63 begin to contact the wire 7, and the wire 7 will be the upper conductive semicircular ring 62 and the lower conductive semicircular ring 63 are compressed in the direction of the compression spring 66, and the upper conductive semicircular ring 62 and the lower conductive semicircular ring 63 start to rotate along the articulation until the upper conductive semicircular ring 62 and the lower conductive semicircular ring 63 are enclosed The electric current detection unit 67 detects the induced current in the annular electric conductor, thereby detecting the electric current in the wire 7. When the detection is completed, the walking device 5 moves to both ends of the horizontal guide rod 2, the compression spring 66 pushes up one end of the upper conductive semicircular ring 62 and the lower conductive semicircular ring 63, and the wire 7 is removed from the circular conductive body .

[0019] Preferably, the horizontal guide rail 2 is arranged above the center of gravity of the drone 1. When the drone stops between the two wires 7, the stability is good. It will not roll when blown by the wind.

[0020] See Figure 4 As shown, the horizontal guide rail 2 is an I-beam, and the walking device 5 includes rollers 51 and a motor 52. The grooves on the left and right sides of the I-beam are provided with a roller 51, and one of the rollers 51 is connected to the motor 52. The motor 52 can be directly connected to the roller 51 or can be connected to the roller 51 through a gear. In order to keep the center of gravity stable, the motor 52 and the Hall sensor assembly 6 are distributed on the front and rear sides of the horizontal guide 2.

[0021] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or replacements that are not thought of through creative work shall be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
